![]() ![]() ![]() High-energy visible (HEV) blue light penetrates the eye deeper than UV light does, but like UVR, cumulative exposure can damage our retinas, the part of the eye that houses the sensitive cells responsible for vision. That means that any digital devices that uses LED screens (TVs, tablets, smartphones, e-readers, computers, etc.) also emit high-energy blue light. Compact fluorescent lights (CFL) and light-emitting diode (LED) lights also emit this type of blue light. Like UV light, the main source of blue light is the sun, but there are many more manmade sources we encounter in our daily lives. It has the shortest wavelength of all visible light, and, therefore, has the highest energy of the visible light spectrum. Part of the visible light spectrum, this type of visible light is the closest to UV light on the light spectrum. What Is Blue Light?Īlthough less well-known than UV light, blue light is another type of light that we have exposure to on a daily basis that can potentially cause damage to our eyes. Proper protection so you can limit overall exposure. Be conscious of the amount of time you’re spending outdoors with or without To mitigate the damage, use sunglasses and hats to keep the UV light wavelengths away from your eyes and wear long sleeves or sunscreen to protect your skin. As we mentioned, UV light damage happens with repeated exposure over time. However, that doesn’t mean we can forgo any further protection. The cornea, the smooth outer casing of our eyes, and the crystalline lens, the piece of our eye that intakes visual stimuli, absorb the majority of UV light that enters the eye. Our eyes have evolved over thousands of years and have developed natural UV protection over time. Although we shouldn’t dismiss these damages, they can generally improve with proper care. The parts of the eye most damaged by cumulative UV light (the continuous exposure over time) are the cornea and lens, or the outermost layers of our eyes. #BLACK LIGHT SCREEN FREE#It can cause oxidative photodegradation, which means things called free radicals are produced in excess and our bodies can’t fight them all, leading to cells being destroyed. However, ultraviolet radiation (UVR) is undoubtedly dangerous to our eyes and the surrounding structures. Though UV light does little to nothing to help us physically see, it does help our bodies produce enough Vitamin D when absorbed in moderation. UVC is mostly absorbed by the atmosphere, but it can cause permanent tissue damage with brief exposure. #BLACK LIGHT SCREEN SKIN#It can cause sunburns, skin thickening, wrinkling, and possibly destroy Vitamin A and damage DNA, leading to several skin-related health concerns.
